20100188987Power learning security in wireless routers - In described embodiments, elements of a wireless home network employ learned power security for the network. An access point, router, or other wireless base station emits and receives signals having corresponding signal strengths. Wireless devices coupled to the base station through a radio link are moved through the home network at boundary points of the home and the signal strength is measured at each device and communicated to the base station. Based on the signal strength information from the emitted signals measured at the boundary points and/or from measured signal strength information of signals received from the boundary points, the base station determines a network secure area. The base station declines permission of devices attempting to use or join the home network that exhibit signal strength characteristics less than boundary values for the network secure area.07-29-2010
20110043725LED LCD Backlight with Lens Structure - In described embodiments, a thin film transistor (TFT) liquid crystal display (LCD) structure incorporates a white light emitting diode (LED) structure for backlighting. White LEDs are formed behind each TFT cell, allowing for display “black” as a function of a nematic layer, on the TFT substrate, while increasing intensity of the LED LCD backlight structure. A lens structure might be formed between the LEDs and the TFT substrate to reduce a number of LED sources for a given backlight intensity.02-24-2011
20110080237AUTOMATIC DE-EMPHASIS SETTING FOR DRIVING CAPACITIVE BACKPLANE - In described embodiments, automatic de-emphasis setting is provided for driving a capacitive backplane. Line impedance and line length of a transmission (TX) device are measured that form a load impedance of a driver. For some exemplary embodiments, the line impedance is predominantly a line capacitance, and such embodiments detect this capacitance. Measured line impedance is converted to a control signal (such as, for example, a three bit digital control signal) which automatically sets the de-emphasis of the TX stage. With the amount of capacitance and the length of the transmission line, the appropriate de-emphasis settings might be determined, and such de-emphasis setting be applied by the transmitter to the driver to compensate for transmission line effects.04-07-2011
20110126028Fast Turn-On/Off for Energy Efficient Ethernet - In described embodiments, turn-on time for active portions of an Energy Efficient Ethernet (EEE) device is improved by storing energy in a corresponding capacitor bank through a bidirectional device from a certain node in the device during an active state, continuing to store the energy when the device enters a Low Power Idle (LPI) state, and then allowing the energy to return to the node through the bidirectional device when the device returns to an active state. During active mode, the bidirectional device controls the capacitor bank so as to charge relatively slowly to store energy, and when the device transitions to LPI, the charge is maintained in the capacitor bank. When the device returns to the active state, the bidirectional device allows the capacitor bank to discharge relatively rapidly to the node, thereby improving the turn-on time of the circuit elements coupled to the node.05-26-2011
20110227794PACKAGE INVERTED F-ANTENNA - In described embodiments, a package inverted-F antenna is disclosed. The inverted-F antenna (IFA) is printed on a semiconductor package, and conductive bonding material is applied to leads of the IFA and terminal pads of a substrate when bonding the package to the substrate holding a semiconductor die. Wire leads couple the output terminals of the die to the terminal pads and, hence, the IFA.09-22-2011
